gcc failing on -G 0 option


I am trying to build a cross compiler to port eCos to
a Mips chip.  I have followed the direction in the web page
"Building the NEC MIPS VR4300 development tools for Linux".
I download the following snapshots and patches:

binutils-000426 (from binutils.tar.bz2)

I was able to compile and install binutils, no problem.

I was able to configure the cross compiler.  However, when I
tried to make it, I get the followin errors:

  LIBGCC2_CFLAGS="-O2  -DCROSS_COMPILE -DIN_GCC    -g -O2 -isystem ./include  -G 0 -g1  -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -Dinhibit_libc " libgcc2.a

The Makefile in /tmp/buid/gcc/gcc states:

# We must build libgcc2.a with -G 0, in case the user wants to link
# without the $gp register.

but I could not find the -G option documented in as.

Can someone help me out?  Is there a patch I need?
